Why is it important to have a control group in the experimental design?
The control group is the main one because it acts as a benchmark to balance the results of the experiment.
What is control group in the experiment?Control groups are a principal aspect of true experimental designs. The presence of control groups authorizes researchers to confirm that study results are due to the drafts of independent variables rather than irrelevant variables. The control group of an experiment is a group that is not revealed to the independent variable and thus serves as a benchmark to which to compare the outcome of the experimental group. An experimental group, also known as a use of group, receives the treatment whose effect researchers wish to study, whereas a control group does not. They should be similar in all other ways.
So we can conclude that an example of a control group is a group of individuals in a detached trial that receive placebo pills instead of medication.

How does resolution of a microscope help you to observe different structures of the cell.
Answer:
The resolution of a microscope or lens is the smallest distance by which two points can be separated and still be distinguished as separate objects.
Explanation: The smaller this value, the higher the resolving power of the microscope and the better the clarity and detail of the image. ♀️

what are the different parts of microscope ?A microscope is which produces large images of tiny substance and provide observer a close view of minute structures at a convenient scale for examination and analysis.
Anatomically the microscope consist of three structural parts, i.e. head, base, and arm, where head is known as the body and it carries the optical parts in the upper part of the microscope.
Base of microscope is used to support and carries microscopic illuminators and Arms connect the base and the head and the eyepiece tube to the microscope base.
The optical parts are basically applied for the view, magnify, and production of an image from a specimen placed and the various parts.
Eyepiece or ocular located at the top of the microscope with standard magnification is 10X, Eyepiece Tube which carries the eyepiece just above the objective lens.

What is the use of reverse transcriptase?Reverse transcriptase enzyme has been generally used by the retrovirus for their genome replication. This enzyme has been discovered by the Howard tenim.
Reverse transcriptase enzyme generates the complementary DNA from the mRNA template by the process of reverse transcription. The presence of RNase H, RNA-dependent DNA polymerase and DNA-dependent DNA polymerase activity enable the enzyme to convert the mRNA into DNA.
The position of the mRNA is to carry protein facts from the DNA in a cell's nucleus to the cellular's cytoplasm (watery interior), where the protein-making machinery reads the mRNA sequence and translates every three-base codon into its corresponding amino acid in a growing protein chain.
Therefore, The mRNA sequence will best match the section of DNA shown below is C-U-A-G-G-A. Thus, option C is correct.

DNA has _____ strands and mRNA has ______ strand of nucleotides
Answer:
DNA has 2 strands and mRNA has 1 strand of nucleotides.
DNA has 2 strands and mRNA has 1 strand of nucleotides.
Deoxyribonucleotides is simply referred to as the fundamental (basic) unit of a deoxyribonucleic acid (DNA).
Basically, deoxyribonucleic acid (DNA) comprises two (2) strands of nucleotides which are arranged in a double helix.
On a related note, a messenger ribonucleic acid (mRNA) refers to a molecule that is complementary to the template strand of deoxyribonucleic acid (DNA).
Hence, mRNA has one (1) strand of nucleotide and it is mainly used for the encoding of protein molecules.
In conclusion, deoxyribonucleic acid (DNA) has two (2) strands of nucleotides while messenger ribonucleic acid (mRNA) has one (1) strand of nucleotide.
